Code P1E29 Saturn Description

The power inverter module, often referred to as the drive motor generator power inverter module, contains three motor control modules and the hybrid powertrain control module. Two of the motor control modules operate their respective drive motor generator based upon power inverter module commands. The third motor control module controls the auxiliary transmission fluid pump motor. The hybrid powertrain control module and the motor control modules share the power inverter module ignition voltage circuit, battery voltage circuits and chassis earth. The motor control modules and the hybrid powertrain control module are part of the power inverter module and are not serviced separately.
The auxiliary transmission fluid pump motor control module uses sensorless control to estimate motor speed and position from the phase current sensors.
